DETAILED DESCRIPTION

Many electronic devices are constructed with two pieces that may bejoined by hinges or various sliding mechanisms. Examples of such devicesmay be hand held mobile telephones, portable gaming devices, laptopcomputer, netbook computers, or other devices.

A protective cover or outer shell for these devices may be constructedwith two hard shell components, one for the front portion of theelectronic device and one for the rear portion. A silicone or otherflexible component may be held by one or both of the hard shellcomponents.

In some embodiments, the flexible component may be held by only one ofthe hard shell components. In an example of such an embodiment, theflexible component may be installed underneath the rear hard shellcomponent.

In some embodiments, the flexible component may be held or retained byboth hard shell components. In an example of such an embodiment, theflexible component may be retained by both hard shell components and theflexible component may have a portion that covers a hinge or othermechanism that may join the two portions of the electronic device.

The flexible component may have pads or other mechanisms that may allowa user to active a button on the electronic device when the cover isinstalled. Some embodiments may have removable covers for earphone portsor other electrical connectors as well.

In some embodiments, the protective cover may be a removable cover thatmay be installed and removed by a consumer. In such embodiments, theprotective cover may have logos, colors, or other designs that allow auser to personalize their electronic device. In such embodiments, theprotective cover may have snaps or other engagement mechanisms that maybe easily installed and removed by a consumer.

In other embodiments, the protective cover may not be a consumerinstalled cover. In such embodiments, the protective cover may beinstalled by the manufacturer of the electronic device and may be anintegral part of the electronic device. In such embodiments, theprotective cover may be installed using fasteners, adhesives, snaps, orother mechanisms for which a typical consumer may not have access orability to install or remove.

FIG. 1 is a perspective view of a protective case 100 and asliding/articulating handheld electronic device 104. Many handheldelectronic devices have a back portion 110 and a frontsliding/articulating front portion 112. Mobile phones, for example, mayhave a sliding front portion that may include a screen that slides to anopen position to access a keyboard. Other mobile phones may have a frontportion, such as sliding/articulating front portion 112, thatarticulates on hinges to expose a keyboard.

In order to provide a cover for both the back portion 110 and thesliding/articulating front portion 112, separate hard plastic shells,such as hard plastic front shell 102 and hard plastic back shell 108,can be utilized. However, plastic shells that attach directly to frontand back portions of handheld electronic devices often do not provide alarge amount of protection, especially against shocks from impacts. Inaddition, hard plastic shells may provide openings to operationalfeatures of the handheld electronic device that further reduces theprotection provided by hard plastic shells.

As illustrated in FIG. 1, the hard plastic front shell 102 has a seriesof hooks, such as front shell hooks 146, 148, 150, and other front shellhooks (not shown), on opposing sides of the hard plastic front shell102, that attach the hard plastic front shell 102 to thesliding/articulating front portion 112 of the sliding/articulatinghandheld electronic device 104.

The hard plastic front shell 102 may be constructed from thermoplasticpolymers and has a hardness generally in the range of 65 to 120 on theRockwell scale for HDPE, acrylic, PP, PVC, ABS, nylon, 10% GF PC. Anarrower range of 105-115 on the Rockwell scale can be used for ABS andPC. These ranges are exemplary only and may vary with specificmaterials. The thermoplastic polymers can be molded, die cast orotherwise formed to a desired shape. Other materials can also be usedfor the hard shell, including metals that can be formed or machined to adesired shape.

The hard plastic front shell 102 may attach directly to thesliding/articulating front portion 112 of the sliding/articulatinghandheld electronic device 104. The hard plastic front shell may allowthe sliding/articulating front portion 112 to slide or articulatebetween an open and closed position without interfering with thesliding/articulating motion provided by a sliding/articulating connector(not shown). The hard plastic front shell 102 may provide impactprotection and may have an elevated surface that may protect thesliding/articulating front portion of the sliding/articulating handheldelectronic device 104 from impacts.

As also illustrated in FIG. 1, a hard plastic back shell 108 has aplurality of back shell hooks 114, 116, 118, 120, 122, 124, 126, 128that attach the hard plastic back shell 108 to the back portion 110 ofthe sliding/articulating handheld electronic device 104. Again, themanner in which the back shell hooks 114-128 attach to the back portion110 of the sliding/articulating handheld electronic device 104 may notimpede the operation of the sliding/articulating front portion 112 ofthe sliding/articulating handheld electronic device 104.

The hard plastic back shell 108 also has a plurality of back shellopenings 152, 154, 156, 158, 160 that are aligned with electronic deviceoperational features 174, including buttons and ports, in thesliding/articulating handheld electronic device 104. The electronicdevice operational features 174 include the operational featuresillustrated in FIG. 1, as well as the device buttons 186, 188,illustrated in FIG. 4, and other operational features that may exist onthe sliding/articulating handheld electronic device 104. The hardplastic back shell 108 can be made from the same materials as the hardplastic front shell 102 with the same range of hardness.

As also illustrated in FIG. 1, a flexible silicone layer 106 is providedthat is disposed in the hard plastic back shell 108. The density of theflexible silicone layer ranges from 50 Shore A to 60 Shore A, but mayvary from 30 to 70 Shore A. In one embodiment, a range of 48-52 Shore Ais used.

The flexible silicone layer 106 is molded to fit directly into, and toconform closely to, the hard plastic back shell 108. The flexiblesilicone layer 106 has a plurality of silicone layer openings 130, 132,134, 136, 138, 140, 142, 144. Each of these silicone layer openings130-144 is aligned with back shell hooks 114-128, respectively.

Each of the back shell hooks 114-128 is recessed inwardly from the outeredge of the hard plastic back shell 108 so as to engage the siliconelayer openings 130-144. The back shell hooks 114-128 are insertedthrough the silicone layer openings 130-144 from the outside of theflexible silicone layer 106 and extend inwardly to the interior portionof the flexible silicone layer 106. In this fashion, the back shellhooks 114-128 are disposed inside of the flexible silicone layer 106,adjacent recessed portions, such as recessed portions 182, 184 inflexible silicone layer 106, which allows the back shell hooks 114-128to engage the back portion 110 of the sliding/articulating handheldelectronic device 104.

By inserting the recessed back shell hooks 114-128 through siliconelayer openings 130-144, the back shell hooks 114-128 are hidden by theflexible silicone layer 106 and a clean and decorative appearance isprovided from the outside of the hard plastic back shell 108. Also,since the back shell hooks 114-128 are recessed inwardly and theflexible silicone layer 106 is recessed outwardly, next to siliconelayer openings 130-144, such as recessed portions 182, 184, there islittle or no deflection of the flexible silicone layer 106 resultingfrom insertion of the back shell hooks, which further assists thecombination of the hard plastic back shell 108 and the flexible siliconelayer 106, to function as a single integrated unit.

Upon assembly, the hard plastic back shell 108 and the flexible siliconelayer 106 may be securely married together as a result of the mechanicalconnection between the recessed back shell hooks 114-128 and thesilicone layer openings 130-144, since the back shell hooks 114-128 areinserted through silicone layer openings 130-144. In this manner, theflexible silicone layer 106 appears to be part of the hard plastic backshell 108 and functions as a single integrated unit. As a result, theflexible silicone layer 106 can be made from a soft, flexible materialthat is more easily capable of absorbing shocks since deformation andmovement of the flexible silicone layer 106 away from the hard plasticback shell 108 is substantially restricted.

The back shell openings 152-160 are aligned with various portions of theflexible silicone layer 106, as disclosed in more detail below. As alsoshown in FIG. 1, silicone layer operational features 180 are disposed inthe flexible silicone layer 106 that are disposed in the back shellopenings 152-160 when the flexible silicone layer 106 is married to thehard plastic back shell 108. The silicone layer operational features 180generically refer to the various pads, portals, access panels and otheroperational features of the flexible silicone layer 106.

FIG. 2 is a schematic perspective view of the hard plastic back shell108. As illustrated in FIG. 2, the hard plastic back shell 108 includesa plurality of back shell hooks 114-128 that are recessed from the outersurface of the hard plastic back shell 108. The back shell hooks 114-128slide through the silicone layer openings 130-144 of flexible siliconelayer 106 (FIG. 1) and are hidden by the flexible silicone layer 106.The silicone layer operational features 180 are disposed in the backshell openings 152-160, as disclosed in more detail below, to preventthe entry of dust, dirt and moisture.

FIG. 3 is a schematic perspective view of the flexible silicone layer106 disposed in the hard plastic back shell 108. As shown in FIG. 3,back shell hooks 114, 116, 118 are inserted through silicone layeropenings 130, 132, 134 in the flexible silicone layer 106. Back shellhooks 114, 116, 118 are disposed on the interior portion of the flexiblesilicone layer 106 for attachment to the back portion 110 (FIG. 1) ofthe sliding/articulating handheld electronic device 104 (FIG. 1). Sincethe back shell hooks 114-118 are inserted through the silicone layeropenings 130-134, back shell hooks 114-118 are not visible from theexterior of the hard plastic back shell 108.

For example, as illustrated in FIG. 3, back shell hooks 120, 122, 124,126, 128 (FIGS. 1 and 2) are not visible since the flexible siliconelayer 106 hides the back shell hooks 120-128, as illustrated in FIG. 3.In this manner, the flexible silicone layer 106 and hard plastic backshell 108 appear as a single integrated unit. Further, back shell hooks114-128, when inserted through silicone layer openings 130-144, functionto securely hold the flexible silicone layer 106 to the hard plasticback shell 108 so that the combined structure functions as a singleintegrated unit. FIG. 3 also includes a pivoting access panel 178, whichprovides access to a port on the back portion 110.

FIG. 4 is an exploded view of the sliding/articulating handheldelectronic device 104 that is aligned with the flexible silicone layer106, which is married to the hard plastic back shell 108. As shown inFIG. 4, silicone pad 162 is disposed in back shell opening 152.Similarly, silicone pads 164, 166 are disposed in the back shell opening154. Silicone pads 162, 164, 166 comprise silicone layer operationalfeatures 180 (FIG. 1), as well as other operational features on theflexible silicone layer 106, such as device buttons 186, 188 that aredisclosed in FIG. 1.

The silicone layer operational features 180 interact with electronicdevice operational features 174. Specifically, silicone pad 162interacts with the device button 186, while silicone pads 164, 166interact with device button 188. Another silicone layer operationalfeature 180 comprises the silicone plug 172 that is inserted in a jack(not shown) in the back portion 110 of the sliding/articulating handheldelectronic device 104.

As also illustrated in FIG. 4, the back shell hook 122 extends throughthe silicone layer opening 136. Similarly, back shell hook 124 isinserted through the silicone layer opening 138. Back shell hook 126 issimilarly inserted through silicone layer opening 142, while back shellhook 128 is inserted through silicone layer opening 144. Each of theback shell hooks 114-128 (FIGS. 1 and 4) attach to an inner surface ofthe back portion 110 of the sliding/articulating handheld electronicdevice 104 to securely hold the assembled flexible silicone layer 106and hard plastic back shell 108 to the back portion 110 of thesliding/articulating handheld electronic device 104 without interferingwith the sliding motion of the sliding/articulating front portion 112(FIGS. 1 and 4) of the sliding/articulating handheld electronic device104.

FIG. 5 is a schematic perspective view of the hard plastic front shell102. As shown in FIG. 5, front shell hooks 148, 150, as well as otherfront shell hooks not illustrated in FIG. 5, securely attach to thesliding/articulating front portion 112 of the sliding/articulatinghandheld electronic device 104. The hard plastic front shell 102, aswell as the front shell hooks, do not interfere with thesliding/articulating motion of the sliding/articulating front portion112 of the sliding/articulating handheld electronic device 104.

FIG. 6 is a schematic perspective view of an articulating handheldelectronic device 600. As shown in FIG. 6, the front portion 602 swivelsaway from the back portion 604 to expose a keyboard 606.

In this manner,protection is not only provided to the front and back faces, but also atthe location where the handheld electronic device 950 hinges, asillustrated in FIG. 10, with a continuous silicone cover.

As disclosed above, the connecting silicone hinge 908 includes pads 916(FIG. 9) that allow activation of buttons 958 (FIG. 10), while theprotective case 900 is in a closed position. In this manner, thesilicone cover 922 provides protection to the handheld electronic deviceand allows activation of buttons in the hinge area of the handheldelectronic device. Further, the combination of the hard plastic covers902, 904 that surround the softer silicone cover 922 provides asubstantial amount of protection to the handheld electronic device thatis not available from either the use of just a silicone cover or hardplastic covers.

The hard plastic covers 902, 904 protect the handheld electronic devicefrom sharp impacts. The shock of hard impacts is spread along thesurface of the hard plastic outer covers 902, 904, and is absorbed bythe silicone cover 922. In this manner, the combination of the hardplastic covers 902, 904 and the silicone cover 922 provides bothprotection and accessibility that has not been available to hinged typeof handheld electronic devices, such as flip phones.

Although the embodiment 900 is shown as a handheld electronic devicethat pivots along a side portion, a silicone hinge can also be providedon a top portion of a protective cover for handheld electronic devicesthat hinge along a top portion. Further, a silicone hinge can beprovided along a bottom portion of the protective cover for handheldelectronic devices that hinge along a bottom portion. Of course, thesilicone hinge can be employed on either side of the protective cover,depending upon which side the electronic device hinges.
